Quizplus · Accepted Answer

One of the defining characteristics of protocells is that they have a distinct inner environment compared to their exterior environment. This separation allows for the possibility of metabolic reactions and other cellular processes to occur within the protocell.

Answer: D
 Self-reproduction has been observed in some protocell models, which is a key characteristic of living organisms. This ability to produce offspring could be a crucial step in the eventual evolution of more complex life forms.
